lELEVATED CONDUIT FOR ELECTRIC WIRES.

SPECIFICATION forming part of Letters Patent No. 428,145, dated May 20,1890.

Application tiled January 22, 1890. Serial No. 337,757. (No model.)

To all whom, t 712/601/ concern:

Be it known that I, HENRY N. RUTTAN, of \Vinnipeg, in the Province ofManitoba, in the Dominion el Canada, have invented certain new anduseful Improvements in Ele- Vated Conduits Vfor Electric Wires; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, in which- Figure l is a sidcelevation et my improved conduit,and Fig. 2 is a cross-section of the same on line fr 0c.

My invention has for its object to provide a number of separate conduitsattached to a truss-girdcr supported by posts, whereby a number etcompanies using` the structure will have their line-wires under separatecontrol, each company using a conduit in which to lay its wires.

My invention consists of a structure coinprisiug a row of ground postsor piers supporting a trussgirder, and conduits attached thereto, theconduits arranged one above the other to carry electric wires inclosedtherein, as hereinafter described.

A A are the ground-posts standing in a row at suitable distances apart,and B is a truss supported by the posts. y

O are conduits secured horizontally to the girder in any suitablemanner, one conduit placed above another and at convenient distanceapart, as circumstances or need may require. The conduits, for cheapnessof construction, may be made of boards nailed together to malte threesides of a rectangular tube in a continuous manner, and provided with asuitable cover or top. The electric wires E are laid in the conduits,each. company using the structure having the sole use of one or moreconduits, whereby one company can obtain access to its own wires Withoutinterfering with the wires of another company using the other conduit orconduits.

The wires are laid in the conduits in any suitable manner to be properlyinsulated. The girder preferably rests on a plate F, bearing on across-head G, on the top of cach post, and secured by braces H from thecrosshead to the upper cord and braces Ilrom the cross-head to thevpost."When the number of conduits to be carried is greater than can beconveniently supported by one truss, two or more may be used.

I claim as my inventionl. A structure to carry overhead electric wires,consisting of a truss-girder, supported by posts A, and one or moreconduits C, secured to said girder, as set forth.

2. The combination, with the posts A, of the truss-girder B, supportedby said posts, one or more conduits O, secured to the girder, and WiresE, laid in the conduits, as set forth.

3. The combination of the posts A, trussgirder B, connecting said posts,conduits C, fastened to the girder, plate F, cross-head G, and braces IlI, as set forth, for the purpose described.

HENRY N. RUTTAN.
